vite 使用 scss 全局变量

1. 安装 sass

bash


npm i sass@1.75.0 -D

2. 配置 vite.config.js

重点是 css 里面 scss 配置

import { fileURLToPath, URL } from "node:url";
import path from "path";
import { defineConfig } from "vite";
import vue from "@vitejs/plugin-vue";
import vueDevTools from "vite-plugin-vue-devtools";

// 引入svg

import { createSvgIconsPlugin } from "vite-plugin-svg-icons";

// https://vite.dev/config/
export default defineConfig({
  plugins: [vue(), vueDevTools()],
  resolve: {
    alias: {
      "@": fileURLToPath(new URL("./src", import.meta.url)),
    },
    extensions: [".js", ".json", ".ts", ".vue"],
  },
  // 配置scss
  css: {
    preprocessorOptions: {
      scss: {
        additionalData: '@import "@/scss/index.scss";',
        javascriptEnabled: true,
      },
    },
  },
});

3. 创建全局样式文件

根目录新建 scss 文件夹下面新建 index.scss 文件

scss

@import "./variables.module.scss";
@import "./mixin.scss";
@import "./sidebar.scss";
@import "./element.scss";
@import "./transition.scss";

html,
body {
  height: 100%;
  margin: 0;
  padding: 0;
  -moz-osx-font-smoothing: grayscale;
  -webkit-font-smoothing: antialiased;
  text-rendering: optimizeLegibility;
  font-family: Helvetica Neue, Helvetica, PingFang SC, Hiragino Sans GB, Microsoft
      YaHei, Arial, sans-serif;
}

#app {
  height: 100%;
}

*,
*:before,
*:after {
  box-sizing: inherit;
  margin: 0;
  padding: 0;
}

a:focus,
a:active {
  outline: none;
}

a,
a:focus,
a:hover {
  cursor: pointer;
  color: inherit;
  text-decoration: none;
}

div:focus {
  outline: none;
}

.clearfix {
  &:after {
    visibility: hidden;
    display: block;
    font-size: 0;
    content: " ";
    clear: both;
    height: 0;
  }
}

variables.module.scss

scss

// https://www.bluematador.com/blog/how-to-share-variables-between-js-and-sass
// JS 与 scss 共享变量，在 scss 中通过 :export 进行导出，在 js 中可通过 ESM 进行导入
:export {
  menuText: $menuText;
  menuActiveText: $menuActiveText;
  subMenuActiveText: $subMenuActiveText;
